For the second time, after spending a season with the Eagles, safety C.J. Gardner-Johnson only played three games with his new team. The first time, in Detroit, an injury in the second game of the season forced him to the sideline until the regular season finale. This year, Houston released the veteran defensive back and will now need to fill his role on the defense. 
According to Aaron Wilson of KPRC 2, another veteran defensive back, M.J. Stewart will be the next man up at the position. A second-round pick out of North Carolina in 2018, Stewart started his career as a slot cornerback for the Buccaneers. He made six starts in his first two seasons but missed 11 games and was waived before the start of his third year.
The Browns picked Stewart up off waivers, and while splitting time at nickelback with Kevin Johnson, Stewart snagged the only two interceptions of his career. He stuck around with the Browns for the final year of his rookie contract, and Cleveland began to give him a bit of run at safety. Though he was still splitting his time between the slot and the defensive outfield, Stewart began to look more comfortable as a defender, grading out as the team’s third-best defender that 2021 season, per Pro Football Focus (subscription required).
As a free agent, Stewart signed with the Texans, and though he’s mostly been a special teamer during his time in Houston, when the depth piece did appear on defense, he was lining up the most as a safety. In those first three years with the team, he was always an available option to sub into the first team defense in case of injuries, and he was called to do so a few times. That’s why head coach DeMeco Ryans feels comfortable turning to him now, in the wake of Gardner-Johnson’s departure.
Stewart may not need to be relied upon for long, though. Veteran safety Jimmie Ward was recently removed from the commissioner’s exempt list as he distances himself from an assault family violence charge. Despite the removal, Ward still isn’t quite ready to return to the field as he remains on the reserve/physically unable to perform list following a pair of offseason foot surgeries. Per Wilson, Ward is expected to be ready to return to practice activities in the next few weeks, barring any disciplinary action on behalf of the NFL concerning the resolution of his legal situation.
Houston will add a bit of depth to the position, as well. Wilson reports that undrafted rookie Zion Childress has been signed to the team’s active roster off of the Cowboys‘ practice squad. Childress has been called up twice by Dallas as a standard gameday practice squad elevation but has only appeared on special teams, so far. With Stewart stepping into the starting role, Childress may stand to fill Stewart’s special teams role with an ability to step up, if necessary.
